+AD4-To be sure you are aware of stuff that may be obvious, although Ferric
+AD4-Chloride is not common in the US for use on PCB, it is the etchant of
choice
+AD4-for a nearby industry, the photochemical machining industry (PCMI), which
+AD4-uses it to etch Copper.  This is the industry that makes lead frames, and
+AD4-solder paste screens.

+AD4-They have an industry association, and we are in touch with them.  If you
+AD4-want info on how to reach them, let me know
